Planning lighting before a renovation: points and switches

Moving a light point after the walls are plastered is costly and messy. How to prepare a lighting plan step by step before renovation work begins.

The renovation decisions people regret most tend to involve electrics. Once the walls are plastered and painted and the ceiling is closed, it turns out there is no outlet for a wall light by the bed, the pendant is in the middle of the room rather than over the dining table, and the hallway switch is hidden behind the door. Fixing these later means cutting into walls again, re-plastering and repainting. When the lighting plan is drawn up at the cheapest stage of the renovation, on paper, most of these costs are avoided.

Step 1: the furniture plan comes before the lighting

Light points serve the furniture, so the plan starts with the furniture layout. Draw a scaled sketch of each room and mark:

• where the bed, sofa, dining table and desk will stand;
• where the kitchen worktop, wall cabinets, island and sink will be;
• which way wardrobe and cupboard doors open;
• which walls will hold the TV, mirrors and pictures;
• where the windows, curtain tracks and air conditioner are.

If the furniture layout is not final, pin down at least the key elements: the head of the bed, the table and the kitchen worktop. Flexible solutions can be found for the rest.

Step 2: lighting layers for each room

Add the three layers on top of the furniture plan: ceiling points or spotlight rows for ambient light; under-cabinet kitchen light, the desk, the mirror and reading spots for task light; and niches, shelves, pictures and coves for decorative light.

Points often forgotten at this stage include:

• wall-light outlets on both sides of the bed;
• a ceiling point above the centre of the dining table, not the centre of the room;
• a cable outlet and power supply position for lighting under kitchen wall cabinets;
• a light outlet beside the bathroom mirror;
• light inside wardrobes and the pantry;
• a socket beside the sofa or armchair for a floor lamp;
• lights on the balcony, terrace and beside the front door.

Step 3: switch positions and logic

Switches should be on the path a person takes when entering a room. The rule is simple: you should find them in the dark without fumbling.

• Place the switch on the handle side of the door, not the hinge side, so the door does not cover it.
• Keep all switches in the home at the same height.
• Plan two-way switching for long hallways, stairs and bedrooms.
• Add a switch by the bed that turns off the main light.
• Control each layer on a separate rocker or switch: ambient, task, decorative.
• If you want dimming, decide on dimmer locations and bulb compatibility in advance.

If you are considering a smart control system, having a neutral wire in switch boxes and deep enough boxes makes later installation easier.

Step 4: technical details

When discussing the plan with an electrician, confirm:

• depth for spotlights in suspended ceilings, and accessible positions for transformers and drivers;
• moisture-resistant fittings and protection zones in the bathroom and kitchen;
• a strong fixing point in the ceiling for a heavy chandelier;
• how lighting circuits are grouped and how many circuit breakers are needed;
• which circuits have residual-current protection: bathroom, kitchen, balcony, yard;
• ventilated spaces for LED strip power supplies.

Keep a photo or copy of the finished plan. Knowing where cables run inside the walls helps you choose safe places to drill when hanging shelves or pictures later.

Step 5: build in spare capacity

Life changes: children grow, a home office appears, furniture gets rearranged. A few extra points are cheap now and expensive later. If the sofa might go in one of two places, put a socket by both. A capped spare outlet in the ceiling can be left for the future. Splitting lighting circuits a little more than strictly necessary also adds flexibility.

Checklist

• The furniture plan is ready and light points follow it.
• Ambient, task and decorative light are considered for every room.
• Switches are on the path of travel, at one height, on the handle side of doors.
• Two-way switching is planned where needed.
• Technical solutions for damp areas, heavy fittings and power supplies are confirmed.
• The plan is saved and spare points are included.

When the work is finished and the fittings are up, their bulbs can come from the Zəfər İşığı range: E27 and E14 LED bulbs, GU10 and G5.3 spot lamps and decorative filament lamps.
